We offer innovative sealing technologies that ensure our clients and partners a sustainable and cost-effective operation of production equipment, while adhering to the highest hygiene and safety standards.
The new generation of FISHBONE technology represents a major technical breakthrough in the world of semi-metallic gaskets, delivering superior sealing performance for static equipment. Its interchangeable design enables easy and universal replacement of all outdated gasket designs, ensuring enhanced protection for assets, people, and the environment.
Our experts are at your service to implement winning sealing strategies and enhance the reliability of your installations.
Why Fishbone?
- Ingenious designSeamless construction. Self-energized by fluid pressure. No potential damage to the flange.
- Strong and durableBalance between robustness and flexibility. The Fishbone cannot be flattened or unwind like a spiral-wound gasket.
- Easily interchangeableInterchangeable with all existing spiral-wound and camprofile gaskets.
- Very low seating pressureBetween 2 and 5 times lower than the seating pressure of camprofile/spiral-wound gaskets.
Fishbone - la nouvelle génération de joints haute performance.
The Fishbone replaces:
Spiral-wound gaskets (from 1912)
(+) Combines the strength of metal strips with the sealing capability of a non-metallic material.
(+) Self-energized by the passing fluid pressure.
(-) Fragility of the gasket (issues with crushing and unwinding of the spiral).
(-) The need for high minimum sealing load leads to bolt deformation and flange rotation.
(+) Self-energized by the passing fluid pressure.

Camprofile gaskets
(+) Solid, does not unwind or crush.
(+) Interchangeable with spiral-wound gaskets.
(-) Less elastic than spiral-wound gaskets, low recovery.
(-) The teeth damage the flange surfaces.
(-) Not self-energized by the passing fluid pressure.
